ATTACHMENT TO COPYHOLDEBS.

Application filed August 31, 1925. Serial No. 53,754.

Copyholders now in use make no provision for holding books. In many cases books must be used in copy work and owing to the fineness of the print, great difficulty is experienced by a typist in following the portions to be copied.

My present invention relates to an adjustable shelf for the purpose of holding and supporting a book on the copyholder before a typistin such a position as to render it easy for her to copy therefrom; and the invention has for its object to provide a simple, strong and serviceable means for supporting a book of any size on a copy holder.

In the drawings:

Figure 1 is a front elevation of the copy holder showing a book in place resting on the adjustable shelf.

Figure 2 is a side elevation showing the shelf in position.

Figure 3 is a modification of the bracket support.

Figure 4 is a side elevation showing the shelf in position when the modification of the bracket support is used.

The type of copyholder to which my improvements are particularly applicable is shown in the patent to Thomas H. Bishop, assignor to Lineatime Manufacturing Co. Inc., No. 1,262,626, dated April 16, 1918, but all of the working mechanism is not disclosed herein for the reason that it is unnecessary to an understanding of the present invention. Suffice it to say that a vertical rod 1 is attached by means of spring clamps 2 or some other suitable means, to each side of the movable copyplate 3 upon which moves up and down the horizontal shelf 4,

to the underneath side of which horizontal shelf 4 is attached a bracket 5, which bracket, when the adjustable shelf has been raised to the proper position, is inclined so that the lower rod thereof rests against the face of the copyplate 3, and is held in position by means of lugs 6, or some other suitable means, and is further counterbalanced by a rod 7 extending from the upper edge of said bracket 5 and terminating in a weighted knob. The numeral 8 indicates a line indicator.

I claim as my invention:

In an adjustment and attachment to a copyholder, the combination of an adjustable shelf sliding on parallel bars attachable to the frame of a copyholder, and said shelf being supported and held in position by a bracket attached to the front part of the shelf, the base rod of said brace being adapted to rest against the surface or face of the frame of the copyholder, and being held in position by lugs, and being further counterbalanced by a rod terminating in a weighted knob attached to the outer edge of the supporting bracket and inclining toward the surface of the copyholder, which adjustment and attachment is for the purpose of holding and supporting a book in position when opened on the adjustable shelf.

In testimony whereof I affix my signature, this 12th day of August, 1925.

GRACE WEBBER,
